Fast, Reliable Roof Replacement Across North Hills
Roof replacement in North Hills usually runs $9,800 to $18,500 for a typical 1,200 to 1,800 square foot single-story tract home, with full tear-offs landing on the higher end because most of these 1950s and 60s houses are carrying two or three stacked shingle layers. We know this because we’ve opened up a lot of North Hills roofs, and we know what’s under them before we give you a number. If you’re off Sepulveda, along Parthenia, or back in the 91343 and 91393 blocks near North Hills Community Park, call (866) 217-3967 and we’ll come out, get on the roof, and show you exactly what you’re working with.
Why Moreno Valley Roof Repair Is North Hills’s Preferred Roof Replacement Company
North Hills homeowners have a specific problem: their houses were built when roofing was cheap to layer and nobody thought twice about nailing a second or third layer over the old one. That means the roofer you hire needs to understand tear-off realities, not just shingle pricing. We’ve replaced roofs across North Hills where the original 1960s cedar shake was still under two layers of composition shingle and a rolled-roof addition. Our crews know what a mid-century gable-to-flat transition looks like, where the old valleys were flashed with nothing but tar, and how Santa Ana winds find every weak seam.
We work with seven major manufacturers, so the recommendation you get from us is based on your roof, your budget, and your timeline, not on whatever brand we happen to stock that week. Ruben Ibarra leads our replacement teams through every North Hills job and is the single point of contact from the first inspection to the final nail.
When you call, we schedule the inspection for a day that works for you, and we’re typically on site in North Hills within a few days. You get a written scope, line-item pricing, and no change orders you didn’t approve in writing first.

Roof Installation in North Hills
Roof Installation in North Hills for our clients means a complete system replacement, not just new shingles over old decking. For a single-story tract home in the 91343 or 91393 neighborhoods, a full roof installation generally falls between $11,000 and $16,500 depending on square footage, pitch, and whether we’re replacing decking or framing on the low-slope rear section. The job involves stripping every layer down to the rafters, inspecting and replacing damaged decking, installing new underlayment and ice and water shield in valleys, setting drip edge, and then installing your chosen shingle or membrane system to manufacturer spec.
North Hills homeowners call us for roof installation when their existing roof has reached the end of its useful life, which in this part of the Valley tends to happen sooner than the manufacturer’s warranty suggests. Valley heat bakes asphalt shingles from above while attic heat cooks them from below. By the time you see granule loss in the gutters or curling at the edges, the roof is usually done.
Full Tear-Off and Decking Replacement
A full tear-off is standard practice on North Hills homes because most have multiple layers and hidden damage underneath. We don’t roof over existing shingles here. The code requires tear-off beyond two layers, and more importantly, the old decking under three layers of 1960s shingle is rarely in shape to hold a new roof for 20 years. We replace decking, fascia, and any framing that the old roof destroyed, and we price it before we touch it.
New Construction and Additions
For additions or new builds in North Hills, we coordinate with your contractor or handle the roof scope directly. New construction lets us start clean, with proper underlayment, proper ventilation, and no old layers to fight. Pricing for new construction roofs runs $8,000 to $20,000 depending on size and material, and we spec materials matched to the existing home’s roofline if you’re adding on.
Roof Replacement Contractor in North Hills
As a Roof Replacement Contractor working across North Hills, the first thing we do is figure out what’s under the existing roof, because that’s where the real cost lives. A straightforward tear-off and re-shingle on a 1,400 square foot North Hills tract home typically runs $10,500 to $14,800 using a mid-range architectural shingle. If the low-slope rear section needs new torch-down or a modified bitumen membrane, add $3,000 to $6,000 depending on access and condition. The shingle itself is not the expensive part. The tear-off labor and whatever we find under it is.
We review every North Hills roof before quoting, and we specify in writing exactly what’s included: how many layers we’re removing, what underlayment we’re installing, what the decking replacement allowance covers, and what happens if we find rotten framing or old wiring chases that need attention. You approve any change before we spend a dollar on it.
Asphalt and Architectural Shingles
Most North Hills homes get architectural shingles now, and the two we install most often are GAF Timberline and Owens Corning Duration. Both hold up to Valley heat better than the old three-tab shingles those houses were built with, and both come with strong wind ratings that matter during Santa Ana season. A full architectural shingle replacement on a standard North Hills ranch runs $10,000 to $15,000.
Flat and Low-Slope Roofing
The flat and low-slope rear sections on North Hills homes cause more leaks than the pitched front slopes. These areas were originally built with rolled roofing or torch-down, and after 60 years of Valley sun they are done. We install modern modified bitumen or single-ply systems, and we address the transitions where the flat section meets the pitched roof, because that’s where water gets in during winter storms.
Trusted Brands We Service in North Hills
We install and service roofs from seven major manufacturers, so when a North Hills homeowner asks about GAF versus CertainTeed versus Owens Corning, we can actually talk through the differences, because we install all three. For budget-conscious replacements, we also work with IKO and Atlas, which deliver solid mid-range performance at a lower cost per square. For homes where wind rating and longevity matter most, CertainTeed and GAF architectural lines are the ones we quote most often in North Hills. We keep local supply relationships in the Valley, which means material lead times are short and you’re not waiting weeks for a special order.

AfterCommon Roof Replacement Problems We See in North Hills Homes
- Stacked shingle layers from the original build: Two or three layers of shingle over the original 1960s roof is the norm in North Hills, not the exception. Every layer adds tear-off labor and hides what’s underneath.
- Rotted decking on low-slope rear sections: The flat back sections on these tract homes collect water and hold it. By the time we strip the roof, the plywood or OSB underneath is often soft and needs replacement before we can lay new roofing.
- Failed flashing at valleys and dormer transitions: Original flashing on North Hills homes was thin metal, often installed with roofing cement that dried out decades ago. Santa Ana winds drive rain sideways into these seams, and that’s where leaks start.
- No ice and water shield in valleys: Current code requires ice and water shield in valleys and around penetrations. North Hills homes built in the 50s and 60s rarely have any at all, and adding it during your replacement is one of the best things you can do for a roof in this climate.
On a 1961 tract home off Sepulveda Boulevard in North Hills, our crew pulled three stacked shingle layers plus the original rolled roofing off the low-slope back section and found punky decking, a soft fascia run, and no ice and water shield in the valleys. We documented each finding, priced the decking and framing repairs in writing, and got the homeowner’s sign-off before we laid new underlayment, set the drip edge, and installed GAF architectural shingles to spec.
Pricing for Roof Replacement in North Hills, CA
Here’s what we’re quoting right now for North Hills homes:
- Full tear-off and architectural shingle replacement (1,200 – 1,600 sq ft): $10,500 – $15,800
- Decking replacement (per sheet of plywood or OSB): $85 – $130 installed, depending on thickness and access
- Flat or low-slope rear section replacement (torch-down or mod bit): $3,200 – $6,500 for a typical 300 – 500 sq ft rear section
- Upgraded underlayment and ice and water shield in valleys: $800 – $1,600 for a standard North Hills roof
- Fascia and eave repair (boards, drip edge, paint): $900 – $2,400 depending on linear feet and damage
The number that moves is the decking and framing line. If your roof has three layers and 60 years of water intrusion, you’ll likely need 6 – 12 sheets of decking replaced, and that’s $1,000 – $1,500 that wasn’t in the original quote from a roofer who didn’t look underneath. We include a decking allowance in every North Hills quote so you’re not blindsided. Call (866) 217-3967 for a free estimate and we’ll give you a real number, not a guess.

FAQs About Roof Replacement in North Hills
Because most North Hills homes are hiding damage under multiple layers of old shingles. The original quote covers the tear-off and new shingles; what it can’t see is rotted decking, failed underlayment, or framing that’s been soaking up water for 20 years. We include a decking and repair allowance in every quote and we get your approval in writing before we do anything outside that allowance. If another contractor’s number jumps after the roof is open, ask whether they inspected the decking from inside the attic before quoting. Call (866) 217-3967 to have us do it right the first time.
In North Hills, you almost always need a full tear-off. Building code doesn’t allow more than two layers of shingles, and most homes here already have two or three from the original 1960s construction plus later patches. Roofing over is also a bad idea structurally. The old layers trap heat, hide moisture, and shorten the life of the new roof. We recommend full tear-off on every North Hills replacement, and we price it accordingly. Call (866) 217-3967 if you want us to look in the attic and confirm what you’re working with.
Line up the line items, not just the total. Does the quote include full tear-off or roof-over? How many decking sheets are allowed in the price? What underlayment and ice and water shield is specified? Is the flat rear section included or quoted separately? We give you a written, line-item bid that breaks all of this out, so when you compare our number to another roofer’s, you’re comparing the same roof. Ruben Ibarra will walk you through the bid line by line if you want.
Ponding water, cracked and blistered rolled roofing, and failed transitions where the flat rear section meets the pitched front slope. Those rear sections were built cheap in the 1960s and they’ve been baked by Valley sun for 60 years. Every Santa Ana wind event drives water under the old flashing and into the low-slope membrane. We address these areas as a full system replacement, not a patch job, because a patch on a 60-year-old membrane buys you months, not years. Call (866) 217-3967 for a free inspection of your rear section.
Yes, and that’s a good thing. When we pull a permit in North Hills and the inspector sees the old roof opened up, they will require current code compliance: proper underlayment, ice and water shield in valleys, correct nailing patterns, and adequate ventilation. If your roof has been layered for decades and the decking shows it, the inspector will require decking replacement before we can re-roof. We know what the North Hills inspectors look for, we build it into the quote, and we pass inspections on the first try. That protects you, not just legally, but from paying for a roof that fails early because code upgrades were skipped.
